Custom Intermediate Relay Solution LL3C-L 10A 3PDT PCB Socket Flange Mount Design Support for Industrial Automation

Custom Intermediate Relay Solution — LL3C-L Series

We do more than supply relays. We engineer relay solutions around your application requirements — custom coil voltage, tailored contact configuration, optimized mounting interface, and integrated protection features. From component selection to system-level optimization, our engineering team partners with you to improve both performance and cost efficiency.

LL3C-L Base Specifications

Beyond Standard Relay Supply

• Custom Relay Design — We tailor coil voltage, contact material (AgCdO, AgSnO2, AgNi), terminal type, pin layout, and packaging to your exact specification. Not a single parameter is off-limits. Custom silk-screen labeling and OEM branding supported.
• Solution-Level Engineering — Our applications team works with your R&D to integrate the relay into your product — PCB footprint optimization, coil drive circuit review, surge protection strategy, and thermal derating analysis. We deliver a validated relay subsystem, not just a component.
• Performance Optimization — Contact material upgrade for higher inrush current, sealed construction for harsh environments, gold-flash contacts for low-level signal switching. We identify the right configuration to extend relay life and improve reliability in your specific use case.
• Cost Optimization — Alternative pin-compatible designs, domestic coil substitution, value-engineered contact material, and volume-based connector/terminal consolidation. Our procurement and engineering teams collaborate to reduce BOM cost without compromising performance.

Typical Applications

Whether you need a drop-in replacement with a custom coil voltage or a complete relay subsystem validated for your industrial product — we deliver engineering, not just components. Contact us with your relay requirements for a technical proposal within 48 hours.
